“Michael Bloomberg might still run for president in 2020, especially if former Vice President Joe Biden winds up not getting in, according to people who have discussed the matter with the former New York mayor,” wrote Axios founder Mike Allen.

“These people tell me that Bloomberg, 77, who announced March 5 that he wouldn’t run, might reconsider if a centrist lane were to open up,” Mr. Allen wrote. “The most likely scenario for that would be if Biden, 76, whose displays of public affection have burst into a major issue, were to stay out or fade fast.”

In a lengthy statement, Mr. Bloomberg advised that he would not make a run.

“I believe I would defeat Donald Trump in a general election,” Mr. Bloomberg said at the time. “But I am clear-eyed about the difficulty of winning the Democratic nomination in such a crowded field.”

He has gotten considerable buzz in the meantime. His potential return to the political arena was picked up by The Hill, New York Post, New York Magazine and The Week, among others.

“Mike Bloomberg is wondering if there’s a silver lining in the Biden debacle,” noted Vanity Fair on Tuesday.

“Bloomberg would be a voice of more moderate practicality in a field where the early campaigning has been dominated by leftish idealism,” Mr. Allen observed, also noting that Mr. Bloomberg — currently worth $58.2 billion — “could command a hearing and impose a footprint in a way that few candidates can.”
